JACOBUS, OF MONTOLAIB, NEW J I EBSEY, ASSIGNOR TO FULLER LEHIGH OOH- PANY, F FULLERTON, PENNSYLVANIA, A CORPORATION OF DELAWARE FURNACE WALL "Original application filed October 28 1927,\Seria1 No. 229,326.

- September, 28, 1928.

This is a division of my application, Serial No. 229,326, filed October 28, 1927. The invention relates to a furnace wall that is especially useful in connectionwith boiler furnaces. The invention will be understood from the description in connection with the accompanying drawings in which Fig. 1 is a side View, partly broken away; Fig. 2 is a section along the line 22 of Fig. 1; and 13 is a section along the line 33 of 151 1t has been found desirable to install the invention along the upper portion of the furnace wall opposite the water tubes of the 15 boiler. This is a portion of the wall that is not subjected to the maximum degree of heat. Since there is not sufficient room to remove the tile from the inside on account of the presence of the boiler tubes, an advantage is obtained with this invention due to the fact that the tile can be removed from the outside. Vertical metal supports 20 are provided at intervals along the outside of thewall and are surrounded on bothsides with 515 insulating material 21. The tile 22 may be removed one at a time from the outside of the furnace.

Each tile 22 is provided with a rounded edge 23 to facilitate inserting and removing 50 the same from the outside as indicated in dotted lines in Fig. 3.

Each tile 22 is provided with two pairs of lugs 24 and 25, the pair of lugs 24 being flush with the edge 23 of the tile and the pair 25 being offset from the other edge a short distance to leave a seat 26. Metal pins 27 pass through holes in the lugs on the tile and corresponding holes in the supports 20. A

sleeve of insulating material 28, such as porce- I lain, is provided for the pins 27 Where they pass through the holes inthe supports 20.

It will be obvious that the tile 22 can be removed from the outside of the furnace wall simply by removing the corresponding pins cated in dotted lines in Fig. 3.

I claim: 1. A furnace wall comprising tile having lugs extending beyond the ends thereof, sup- 27 and pulling the tile outwardly, as indi- Serial No. 308,905.

ports for said tile, and straight pins passing through said lugs and supports.

2. A furnace wall comprising tile having lugs, supports for said tile, and pins passing through said lugs and supports, one'edge of said tile being curved to enable them to pass between said supports.

3. A furnace wall comprising tile having lugs and a curved edge, supports for said tile, and pins passing through said lugs and supports, some of said lugs being offset from the edge of said tile.

4. A furnace wall comprising tile approximately in the shape of a rhomboid in cross section and having lugs on one side thereof,

said lugs extending beyond the ends and sides of said tile.

5. A furnace wall comprising tile having lugs,.spaced supports for said tile, said lugs extending into the spaces between said supports, and means for connecting said lugs to said supports.

6. A tile for a furnace wall having one edgecurved along thearc of a circle of a radius approximately equal to the width of said tile, and lugs upon one faceof said tile.
